COMBINATION HIGH HoIST AND DUMP waoon'.

Application filed June 22,

To all whom it may concern: i Be it known that I, JOSEPH GASSER, a citizen of the United States, residing at 402' Greenwood Avenue, in the city of Trenton, -county of Mercer, and State of New Jersey,

.have invented certain new and useful Improvements in Combination High Hoists and Dump vWagons, of which the 'following is a specification.

This invention relates to wagons and it has more particular reference to motor propelled vehicles of the truck type which are providedwith means whereby their bodies may be inclined for dumping purposes, or raisedand tilted to discharge the contents and thereafter returned to normal position on the vehicle underframe or chassis.

The primary object of this invention is to provide a combined high-hoist and dump wagon having a novel mechanism for raising the body portion high to empty its contents, or simply inclining the same relative to the'underframe or chassis for ordinary dumping purposes. (Another object of this invention is to provide a combination hi 'h-hoist and dump wagon having a novel orm of power takeoff and reverse mechanism-the same being automatic in action in so far-as the throwing so -of, said mechanism into neutral position is concerned when the wagon body reaches its limits of movement. v

With the foregoing and other objects in view, as will become more apparent from the following description, my present invention consists essentially in certain novel features of construction, combinations and arrangements of parts hereinafter fully described and more specifically defined by the subjoined claims.

' 1n the further disclosure of the invention reference is to be had to the accompanying sheets of drawings, constituting a part of this specification, and in which like characters of reference designate the same or cor-v responding parts in all the views.

Figure 1 is a side elevation of a motor truck or wagon having my present improvenients applied thereto, the wagon body and its hoisting and inclining mechanism being 1922. Serial No. 570,159.

shown in the high-hoist position and partly broken away, while the dotted line position is indicative of the ordinary dumping inclination of the wagon body portion.

Figure 2 is an enlarged detail elevation of the worm drive hereinafter more fully explained.

Figure 3 is an enlarged broken and partly sectional detail view of the power take-off mechanism.

F igure 4 1s a front end view or elevatlon of the wagon body raisingand lowering means; and

Figure 5 is a sectional detail of the mechanism for effecting the body raising and lowering, and illustrating its manner of support from the wagon chassis or underframe.

Referring more particularly to theviews the numeral 5 designatesthe chassis or underframe of an ordinary motor truck, 6 the wheels therefor, 7 the'motor, 8 the drivers hood or cab, 9 the steering wheel, 10 the brake control and 11 the transmission gear case or box, all of said parts being briefly enumerated but forming no part ofmy pres cut invention.

According to my present invention and as illustrated, the dump box or body 12 is built in accordance with any of the well known or standard forms and it is fitted on its so underside with longitudinally opposed channel beams 13 of appropriate size -'-and dimensions. Transversely of the chassis 5 and near the rear endthereof, I mount a pair of bearings 14in which are journaled 'a 35 cross-shaft 15, said cross-shaft serving as a support for therear ends of a pair of longitudinal links or rock-levers l6 suitably braced in rigid spaced relation by diagonal ties 17 riveted or otherwise secured together so at their point of intersection by means of a through bolt or rivet 18. Suitably journaled or otherwise mounted in the, forward or free ends of the aforesaid longitudinal links or rock-levers 16 is a transverse shaft at 19 fitted with anti-friction rollers 20 at its free ends, and said rollers 20 are of appropriate size and dimensions to freely traverse the aforesaid opposed channel beams 13 as will be clearly understood on an examina- 13 in the rear of the rollers 20 is a second transverse shaft 21 on which are coupled'the upper ends of a pair of spaced links 22 the forked other ends 23 whereof are pivotally connected by a cross shaft 24 with the up per ends of toothed arcuate racks 25 the lower or free ends whereof are in mesh with pinions or shrouded gears 26 securely keyed or, otherwise mounted on a transverse shaft 27 journaled in bearings 28 bolted or otherwise secured in the aforesaid chassis 5, as will be clearly understood by those acquainted with the art to which my invention appertains. This last mentioned transverse 'shaft'27 passes through a gear box or housing 29 that is supported on an angle bracket 30-Figure 4-connected in any of the well known ways to one side of the chassis .5.

Secured or mounted on the aforesaid shaft 27 in the gear box or housing 29 is a worm wheel 31 in gear with a worm drive 32 integral with a longitudinally disposed drive shaft 33 fitted with universal couplings 34 and j'ournaled at its other or forward end in bearings 35 provided for the purpose in a power take-off box or casing 36-.bolted or otherwise secured by bolts 37 on the transmission gear case or box 11. Freely mounted on the aforesaid shaft 27 in the power take-off box or casing 36 in opposed rela-.

tion area pair of miter gears 38, 39 in mesh with an intermediate gear 40, and it is to be noted that one of the gears-+38 for example-is provided on its boss with a pinion 41 in gear with a toothed wheel 42 journaled on a stub axle 43 supported in appropriate bearings 44 in the aforesaid power take-off box or casing 36. This latter toothed wheel 42 is in turn driven by a gear wheel 45 from the jack shaft-not shownin the transmission gear case or box 11. Feathered or otherwise slidably keyed on the shaft 33 intermediate the miter gears 38, 39 is a grooved sleeve or clutch member 46 with which co-operates a stirrup fork 47 on a longitudinally disposed rod '48 passing through said power take-ofl box or casing 36 and a hearing or bearings 49 provided for the purpose pendent from the chassis or underframe 5. This longitudinally disposed rod 48 is movable by means of a hand lever 50 appropriately mounted on a ivot 50 in thedrivers hood or cab 8 an it will be readily understood that when said rod 48 is moved for example forwardly it will draw the sleeve or clutch member 46 into operative engagement with the outer gear 38 and through the mechanism hereinbefore described will rotate the shaft 33 and through the worm drive 32 effect the raising of the arcuate racks 25. a

In order to provide means for retaining the aforesaid arcute racks 25 in operative engagement or mesh with the pinions 26, I employ grooved or flanged idlers 51 of suitable dimensions to fit the back of the racks 25, and said idlers 51 are conveniently and freely mounted on stub axles or bolts 52 carried by the aforementioned bearings 28, and as will be well understood by those conversant with the art to which my invention appertains.

In order to provide an automatic knock out for the raising and lowering mechanism, I preferably extend the aforesaid rod 48 rearwards into close proximity with one of the arcuate racks 25 and fit the end of said rod 48 with a forwardly curved arm 53 pivoted on the chassis 5 which is adapted to cooperate with a'laterally projecting lug 54 outstanding from said rack 25. Thus it will be readily understood that when the rod 48 is longitudinally moved forwardly,-it will carry with it or correspondingly advance the curved arm 53 so that as the co-operating arcuate rack 25 reaches or nears its limit of upward movement--for examplethe projecting lug 54 thereon will contact with said curved arm 53 and through the rod 48 move the vgrooved sleeve or clutch member 46 into neutral position.

Fitting longitudinally parallel with one or both of the spaced links 22 is a rod 55 provided at its forward end with a latch member 56 slidably fitting a slot orguide 57 in said link 22. This latch member 56 is adapted to engage ina notched out part 58 in the headed end 59 of the co-operating arcuate rack 25, and as will be best seen from Figure 1. The aforesaid rod 55 is operable or movable by a bell crank handle or the like 60 pivoted .at 61 to the adjoining channelbeam 13. The unlatched position of the spaced links-22 is ,shown on Figure 1 in dotted lines and 'itiwill be clearly apparentthat when said links 22 are unlatched from the racks 25 the "dump box or body .12 will be tiltable for ordinary dumping purposes in contradistinction to the high-hoist movement.

The construction, assembly and interrelation of the several parts having been fully described, it will be clearly apparent that when the dump box or bodyv 12 is resting in a horizontal or the normal position on the chassis or underframe 5, and it is desired to elevate the same to the highhoist position, as shown by the full lines in Figure 1, the operator or driver of the truck will move the hand or control lever 50 forwards from the neutral position. This movement of the control lever 50 will shift 38 and through the gears 41, 42, and 45 effeet the rotation of the power take-ofi' or drive shaft 33. This rotation of the shaft 33 in the re uisite direction will result in the driving 0 the worm 32 and worm wheel 31, and through the pinions or shrouded gears 26 eifect the arcuately swinging elevation of the racks and assuming that the spaced links 22 have been latched to the headed ends59 of said racks 25 as hereinbe fore described, it will be clearly apparent that the dump box or body 12 will be elevated and inclined as shown by the full lines in Figure 1. Now it will be perfectly obvious that as the racks 25 approach their limit of upward movement, the projecting lug 54c thereon will engage the curved arm 53. and thereby move the rod 48 forwardly and automatically shift the sleeve or clutch member 46 into neutral position and thereby disconnecting the raising and lowering mechanism'tfrom the power take-off mechanism of tire wagon. Similarly a reverse movement of the hand lever 50 will shift the sleeve or clutch member 46 into mesh with the miter gear 39 and 'efiect the return of the dump box or body 12 back to its normal positionon the chassis or underframe 5. On the other hand when it is simply desired to dump the box or body 12, as indicated by the dotted line position in Figure 1, the latching means or members 56 will be retracted from connection with the headed ends 59 of the racks 25, thus rendering the link members 22 inoperative for raising purposes, whereupon it will be readily seen that the dump box or body 12 will be upwardly swung or inclinedon the shaft 15 as a pivot.

It is also to be noted that as the dump box or bod 12 returns to or approaches its normal or ,orizontal position on the chassis 5, the co-gperating link or rock lever 16 vwill contact with the upper curved part of the arm 53 and thereby rock same on its pivot 53 "to efiect the movement of the clutch 46 back into neutral position, the same being obvious to those conversant with the art a); which my invention relates.

From the foregoing description and exlan'ation of the o eration of my invention, its simplicity an "usefulness will be self evident, while its easy application tonew or existing motor trucks will be clearly apparent without further description. 1

.While I have shown and minutely described one practical or preferred embodiment of my invention, it will be clearly apparent that the same is susceptible of many detail changes, and the right is accordlngly hereby reserved to make all such reasonable changes and variations, or other combine tions or the several'parts as fairly lie within the scope of the a pended claims.
